the window stool when the easement is partlyopened, make it difficult touse the orthodox hinged window screen. One of the special disadvantagesof the hinged screen is due to the fact that said screen must openinwardly and in so doing the upper part of the screen frame contacts thedrapes of the window and disturbs their hangings and sometimes tearssaid drapes close to the head of the window. Where Venetian blinds areused either on sash or casement windows, there is no room to place a flyscreen between the blind and the sash and frequently the width of theblind laths is such as to preclude the possibility of hinging a flyscreen on the inside of the window frame. It is with the object ofavoiding these defects that the contemplated invention is designed.

The invention consists of a foraminous screen having substantially rigidframe members on two opposing marginal edges and flexible non-metallicbindings on the remaining marginal edges, as will be more fullydescribed in the following specification and shown in the accompanyingdrawing, in which- Fig. 1 is an elevational view of the screen as viewedfrom the interior of the room.

Fig. 2 is a detail sectional view of the upper border of the screen.

Fig. 3 is a detail sectional view of the lower border of the screen.

Fig. 4 is a detail sectional view of the side border of the screen.

Fig. 5 is a detail sectional view showing the preferred form offastening of the screen to the window frame.

In the drawing like characters of reference indicate corresponding partsin each figure.

The numeral l indicates a window frame having stiles 2, a head 3, acasement sash 4 and a stool 5. The casement sash is presumably providedwith a casement fastener 6 and a casement stay I. Fitted to the innerface of the stiles 2 and the head 3 are brackets 8, which preferablysupport the stem portion 9 of a so-called Lift the Dot fastener l0.Detachably connected to the stem portions 9 by clip portions ll of thefastener I is a wire screen l2 which is the subject matter of theinvention.

The screen I2 is provided on its side edges with borders M, on its upperedge with a border l and on its lower edge with a border 16. Theseborders are formed with a strip or web of flexible textile material H orany other suitable material such as rubber or the like. Where textilewebbing is used it is folded upon itself and upon the edge of the screenmaterial and is stitched as at l8 in any appropriate manner as shown inFigures 2, 3 and 4. The upper border [5 and the lower border l6 are eachprovided with a stiffening rod 19 which serves to prevent the edge towhich it is applied from bending to any serious extent. The webbing llof the lower border 16 is preferably of greater width than that on thesides and upper edge of the screen l2, so that the stiffening rod [9 maylie above the level of the bar 20 of the casement stay I.

The screen as shown in Figure 1 is clipped along its top border l5 andboth side borders I4, the webbing [1 serving to intimately contact withthe window frame members.

When it is necessary to open the easement sash 4 the lower corner of thescreen adjacent the easement fastener 6 is drawn inwardly as shown,causing the fasteners H) to become disconnected on that side of thewindow and allowing the lower side portion of the screen to be foldedback and afford access to the easement fastener 6, and to the stay I.When the sash is locked in adjusted position the corner of the screen isallowed to drop and the clip fasteners l0 are pressed together tocomplete the closure. If the bar 20 of the stay 1 projects inwardlybeyond the plane of the screen the strip I! of the border will drapeover said bar and leave only a small gap immediately below said bar.

It will be obvious that the side borders of the screen may be stiffenedwith the rods l9 and the top and bottom borders left as flexible membersas an alternative equivalent structure.

It is also contemplated that the bottom border may be provided with afringe to extend from the height of the bar 20 of the stay I to thesurface of the stool 5.

What I claim as my invention is:

1. A window screen comprising a sheet of wire mesh, a strip of textilefabric folded along a medial line forming a border for' each of themarginal edges of the wire mesh, said wire mesh extending into the foldof each strip and tenninating'at a line remote from the fold, the outerfolded portions of said strip lying in intimate contact with each other.

2. A window screen comprising a sheet of Wire mesh, a strip of textilefabric folded along a medial line forming a border for each of themarginal edges of the wire mesh, said wire mesh extending into the foldof each strip and terminating at a line remote from the fold, the outerfolded portions of said strip lying in intimate contact with each other,two opposing marginal edges of said wire mesh being provided withstiffening rods intermediate the width of the folged textile fabricstrip and remote from the fa LAWRENCE BRADSHAW.
